SWIN GLETREE DEVICE.

Specification of Letters Patent.

Patented Sept. .22, 1914.

To all whom it may concern:

Be it known that 1, JOHN E. MoGRiiNER, a citizen of the United States, residing at Harrisburg, in the county of Saline and State of lllinois, have invented certain new and useful Improvements in Swingletree Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to trace connectors, and more particularly to that type of connector which provides means for pre enting the accidental disconnection of the trace from the swingle-tree.

The object of this invention is to provide a device of the kind above described that is simple in construction. eliicient in operation, and is composed of the minimum number of parts.

With these and other objects in view. this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a plan view of the improved device in use. Fig. 2 is a perspective view of the improved trace connector. Fig. 3 is a longitudinal section taken through the trace connector. Fig. 4 is a section taken on line 4-4 of Fig. 3. Fig. 5 is a section taken on line 5 5 of Fig. 3. Fig. 6 is a perspective view of the ring yoke used with this device. Fig. 7 is a perspective view of the locking plunger used with this device. Fig. 8 is a side elevation of the socket member.

Referring to the parts by reference numorals, a swingle-trcc is designated by 10 and is connected to the trace connector by means of the ring 12 formed at one end of the socket member 13. Suitable means can be provided for the securance of the trace connector to the swingle-treein the drawings a screw is provided. This socket member 13 is provided with a socket 14. said socket 14 being formed in the opposite rnd of the socket member 13 from that of the ring 12, and is provided with an enlarged portion at one end thereof forming a shoulder 15, the purpose of which will be hereinafter set forth. A locking collar 16 is rotatably carried by socket member 13 and is provided with a cut-away portion 16 and an elongated notch 17 This locking collar 16 comprises a band of material secured at its abutting ends by means of the nuts and bolts 18.

A housing 19 is secured to the outer face of the locking collar 16 by means of the feet 20 through which the rivets 21 pass, and said homing contains a plunger 22, said plunger l aving an upwardly extending thumb engaging member 23 which extends through an opening formed in the housing 19. A coiled spring 24 is positioned in said housing and engages one end of the plunger 22 for normally urging the plunger in a positicm as shown in Fig. 3. A locking eye 25 is carried by the socket member 13 and is adapted to receive the end of the plunger 22. An eye yoke 26 attached to the trace 2? and is provided with a lug comprising a neck 28, and an enlarged head 29. said head tapering toward one end to facilitate the placing thereof in the socket 14 of the socket member 13.

The operation of this device is as follows: The eye yoke 26 is placed in engagement with the socket member 13 by inserting the neck 28 and the enlarged head 29 in the socket 14. the tapering end of said enlarged head fitting snugl in the enlarged portion of the socket 14 and having one face abutting the shoulder 15. The locking collar is then moved upon the socket member 13 so as to cover the openin in the socketmember caused by the socket 14. This locking collar is turned upon the socket member 13 until the plunger 22 carried in the housing 19 comes into alincmcnt with the eye 25. he end of the plunger 22 is then placed in the eye 25 by the operator. and the tension of the spring keeps the same in the eye until it is desired to withdraw the same. It will be seen that the collar 16 can easily be rotated inasmuch as the eye which is secured to the socket member -43. moves in the elongated notch 17. \Vhen it is wished to withdraw the eye yoke from the socket memher all that is necessary is to remove the plunger from the eye, rotate the locking collar until the cutaway portion 16 becomes placed over the opening formed in the socket member 13 by the socket 14. The eye yoke 26 can then be removed. It will be seen from the drawing that the locking collar 16 cannot accidentally slip otlt of the socket member 13 because of the shoulders 30 and 31 formed at both ends of the socket member 13.

It is obvious that minor changes may be i made in the form and construction of this invention without departing from the spiritthereof. It therefore not wished to confine the invention to the exact form herein shown and described, but it is wished to inelude all such as properly come Within the scope claimed.

\Vhat is claimed, is z 1. A device of the kind described comprising a socket, member provided with an eye at one end adapted to fit over the end of a swingletrce, said socket member provided with a socket at the opposite end from that of said eye, an eye yoke having a lug at one end thereof, said lug adapted to fit in said socket in said socket member, and rotatable means on said socket member for holding said lug in said socket.

2. A device of the kind described comprising a socket member with an eye at one end adapted to fit over the end of a swingletree, said socket member provided with a socket at the opposite end from that of said eye, an eye yoke having a lug at one end thereof, said lug adapted to tit in said socket in said socket member, and means passing around said socket member and over said lug for holding said big in said socket of said socket member.

3. A device of the kind described comprising a socket member provided with an eye at one end adapted to fit over the end of a swingle-tree, said socket member provided with a socket at the opposite end from that of said eye, an eye yoke having a lug at one end thereof, said lug adapted to fit in said socket in said socket member, said socket member provided with shoulders at both ends, a ro ;al. lc locking collar on said socket member between said shoulders. said cellar provided with a cutaway portion adapted to be positioned in alincment with the o iening formed in said socket member by said socket when in an open position, and means for holding said collar against move ment when said cut-away portion is out of alinen'ient with said opening fii rmed in said sccket member.

at. A device of the kind described comprising a socket member and a member adapted to lit in the socket of said socket member, and a ring means carried by one of said members for holding said second mentioned member in said first mentioned member.

5. A device of the kind described comprising a socket member adapted to be carried by a swingle-trce, an eye yoke having a lug at one end thereof adapted to fit in the socket of said socket member. a collar rctatably carried by said socket member for holding said lug in said socket member and means for preventing the longitudinal movement of said collar on said socket member.

in testimony whereof I hereunto a'iiix my signature in presence of two witnesses.
